Hi Diane. THere are several ways to measure this now. The old way :
"nitrogen balance"=<Nitrogen intake>-(<urine urea nitrogen> + 4 grams)
nitrogen intake ~= protein intake/6.25
<>=integrated over 24 hours. (Must save all urine.)
urine urea nitrogen=urea concentration*volume
: 2. Anyone know the clinical symptoms of loss of nitrogen balance?
Loss of? You might mean imbalance. Negative --> catabolism.
Positive --> growth. Ideally it is +4 - +6 if you are healing.
Negative nitrogen balance also occurs if you're diet has bad amino
acid ratios. I'd think you'd have a craving for, say, milk if it was
negative. Hope this helps some.
